test: Add missing dependency (#614)

Fixes #613

some packages depend on the newest dev version of dbapi, which isn't published yet
when a package in a virtualenv is installed, it will attempt to install those dependencies, which searches on pypi

Installing the local package ensures that 0.7 is installed, so pip sees that and skips trying to resolve against pypi (when it won't find the version).
